There are about 83 clinical studies being (or have been) conducted in Paraguay. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This study is divided into two parts: Part 1: An interventional study, with a pre-post study design to determinate the grade of knowledge of established GC risk factors. Part 2: An observational study to know impact on prevalence and infection eradication of H. pylori
Observational study (cohort type) of advanced GC patients that will be recruited prospectively to study biological factors associated with the disease and relevant clinical outcomes.
The study uses a case-control design that examines the differences in types of exposures between cases defined with a pathological confirmation of GC diagnosis, and controls, defined as patients to whom a gastroscopy was indicated and confirmed absent of GC i
This study is a First-in-Human, single site, prospective, randomized, controlled evaluation of the safety and effectiveness of the Healionics STARgraft AV hemodialysis access graft. The STARgraft has been demonstrated in preclinical studies to have improved resistance to the common failure mode of venous anastomosis stenosis. Performance of the STARgraft AV will be compared against control implants of commercially available standard ePTFE grafts approved for the same use. The study is enrolling patients with End Stage Renal Disease (ESRD) requiring hemodialysis via a prosthetic vascular graft. The study proposes to: 1. Demonstrate improved primary patency of the investigational STARgraft AV compared to the ePTFE controls over a period of 6 months, with extended results to 1 year. 2. Verify safety of the STARgraft AV multilayer construction in extended vascular access use. It is intended to enroll 25 subjects each for the investigational devices and the controls respectively (50 total) with randomized device allocation at subject presentation for implant surgery.
Pediatric traumatic brain injury (TBI) is the leading killer of children worldwide but effective treatments for TBI are limited. Although evidenced-based pediatric TBI guidelines exist, adherence to these guidelines is low,leading us to develop a new Pediatric Guideline Adherence and Outcomes (PEGASUS) program to increase TBI guideline adherence. We propose to test the PEGASUS program's ability to improve TBI guideline adherence and outcomes.
Prospective, single-center study to evaluate the everlinQ endoAVF System when used to create an endoAVF in hemodialysis patients. This study aims to investigate expansion of the percutaneous venous access location to the superficial system which may provide additional procedural benefit.
Objective: To establish the efficacy of laser application with chemical treatment in dental bleaching compared to chemical treatment alone. Methods: The investigators conducted a randomized controlled trial (RCT), single blind (evaluator), in 24 patients randomized to laser and chemical intervention (12) or chemical intervention aloe (12). The commercial products used were Whiteness Hp 35% Hydrogen Peroxide and the LASER of DCM Equipments. The trial outcome measures were obtained using the Vita EasyShade Spectrophotometer and the International CIELCh system. To stablish differences before vs. after treatments and between groups, the T test and chi2 tests were applied.
Study conducted to confirm phrenic nerve stimulation using the a transvenous Phrenic Nerve Stimulator in the left jugular vein.
The objective of the BOSS Study is to assess acute anatomical and geometric annular and ventricular changes that occur when strategically positioned an external inflatable chambers are applied to the outside of the heart.
A single-center feasibility study in patients undergoing cardiac catheterization, to investigate the acute hemodynamic effects of transvenous cardiac autonomic nerve stimulation.
